I think it depends on what do you want to do next. If going into academy, master's/PhD degree, then I would say that it helps a lot to have one article published. However, if you are thinking going enterprise, I think most of those people do not care much about publications.
It also depends on the quality of your work. If it is something really good, I think it might be worth going.
Have you asked the University or your advisor for funds to go? If your work is really good, I think the University would have no problem at all paying for your expenses.
